B'efit known that I, FRANK W.' EDWARDS, a c'itizenof the United States,residing at Logansport, in the'county of Cass and State of Indiana, haveinvented ya certain new and useful Improvement in Auxiliary rOil-Cupsfor Sight-Feed Lubricators, of which. the fol.-

lowing is a full. clear, andexact description.

In the use of 'condensation-displacement sight-feed lubricators it issometimes necese sary to replace or supplement thefeed of oil 'from theoil-bowl to one or more ofthe sightfeeds by anauxiliary oil-cup, and itis a com-l mon practice to construct such lubricators with facilitiesfor introducing these auxiliary oil-cups.

i The present invention is concerned with this sort of apparatus, andtheobject of the invention is to provide an auxiliary device that may beapplied to the upper feed-arm of the lubricator, so that the auxiliarysupply of oil can bedelivered to the upper feed-arm and into theoil-pipe without shutting off the lubricator steam or engine throttle.

' the lubricator of Fig. 1.

In the accompanying drawings, illustrate ing the invention, in theseveral 4figures of which like parts are similarly designated,

'Figure 1 is an elevation of a locomotive-lubricator of theclassdescribed having two auxiliary oil-cups applied to its cylinderfeeds..vFig. 2 is a cross-section, partly in end elevation and on a largerscale, of a portion 4of Fig. 3 is a crosssection of a modification. f

The oil-bowl 1, condenser 2, circulatingpipes 3, water-'valve 4,pipe-plug 5, .pressurevalve 6, steam-chest or cylinder sight-feeds 7,air-pump sight-feed 8, observation glass or index 9, oil-bowldrain-valve 10, filler-plug 1.1, and other parts shown, but notparticularly described, may be of usual or approvedv construction and'are here shown as of the construction known on the market as the Chicagolocomotive-lubricator, Class C, but it is to be understood that thepresent invention is not'limited to its use with that form oflubricatoralone.

As shown, the auxiliary oil-cups 12 are provided with nipples 13,screwed into the nipples of theupper feed,-arms 14 of the Since theseoil-cups are alike, a description ofone will suiiice for both. Theoil-cup, preferably,

fis cylindrical, with Aa saucer-shaped' top'15,

having afilling-hole 16 made as a valvesseat. The filling-plug' 17 is'adapted to be seated in the filling-hole and has a screw-threadedextension 18 screwing into a hollow boss, 19, rising-from thebottoi'n 20.This extension has a lateral hole 21 above the'boss'and intersecting alongitudinal hole 22, opening at the bottom of the extension and withinthe boss. The' boss is pierced transversely at the bottom and in linewith the nipple 13 andthe opposite nipple 23. lThis nipple'23 supportsthe oile'cup feed-valve 24, which has screwthreaded engagement therewithand extends through the opening in the boss, and its point is coned toserve as a valve in a seat 25 in the nipple 13. The oilecup has adrain-valve 26 in its bottom, which drain-valve is made as a screw-plughaving a longitudinal bore 27, intersected by a lateral bore 28. Theupper feed arm 14 has the pressure controlling valve 29 seating in thetop of the sight-feed, and the same I'itting has a tallow-pipeconnection 30.

Instead of the filler-plug 17, screwed into the boss, rising from thebottom of the oilcup I may use an oil-cup 31, Fig. 3, having ascrew-threaded hole 32, in which is screwed One side of the oil-cup ismade with a channel 34, opening at its top at 35 into the oil-cup andhaving an opening in its bottom for the reception of the plug or valve24. Both forms of oil-cups operate in substantially the same Way-that isto say, the oil lcontained therein is displaced by steam-pressure-in onecase through the channel formed by the bore 21 22 and in the othercase-by the channel 34 35. The -water of condensation overflows .throughconnection 30. I

i In order to fill the cup, it is first drained thoroughly by openingthe drain-plug 26. Before the drain-plug is opened, however, the valves24 and 29 are closed, and the fillerplug yis opened suiciently to ventthe cup. After the cup is drained the valves are closed and theiillereplug is opened wide, and then the oil is poured into the cupthrough the filler-plug, and after the oil-cup is filled then theller-plug is screwed down tight to its seat and feed-valve 29 is openedwide, per- Initting the pressure from the upper feedarm to pass into thebottom of the oil-cup and effect the movement or feeding of the oil.Each of the channels shoWn by parts 21 22 or 34 35 constitutes asort ofcirculating-passage, Which prevents the oil from stagnating in the to ofthe cup.

hat I claim is- 1. In a sight-feed lubricator, an oil-bowl, a sight-feedadapted to loe supplied with oil from the oil-bowl and having an upperfeedarm provided With a pressure-controllingvalve, in combination Withan auxiliary oilcup applied in the upper feed-arm and in communicationWith the pressure-controlling valve, and having itself an independentpressure-controlling valve7 and an oil-circulating channel.

2. An auxiliary oil-cup having means for directly applying it in theupper feed-arm of a sight-feed lubricator, and also having a topfilling-plug, a pressure-controlling valve arranged in its bottom, andan oil-circulating channel controlled by said valve.

3. An auxiliary oil-cup for sight-feed lubricators, having afilling-plug in its top, a

boss into which said filling-plug screws, an oil-circulating channel insaid plug, means to connect the oil-cup With the upper feed-arm of asight-feed, and an independent pressurecontrolling valve arranged in theoil-cup and controlling the admission of pressure into the oil-cup andthe discharge of the oil therefrom.

4. An auxiliary oil-cup for sight-feed lubricators, having aiilling-plug 1n its top, a boss into which said iilling-plug screws, anoil-circulating channel in said plug, means to Vconnect the oil-cup withthe upper feed-arm of a sight-feed, an independent pressure-controllingvalve `arranged in the oil-cup and controlling the admission of pressureinto the oil-cup and discharge of the oil therefrom, and an oil-cupdrain-plug.
